Ok, here we go.

Remove the top of the agitator.

Remove the cover just under the top of the agitator.

Now you will be able to see the bolt that holds the agitator in place.

Remove the bolt from the agitator.
Take hold of the bottom of the agitator and pull up on it to remove it from the washer.
Now set the agitator on the floor and hold the bottom half with your feet and pull up on the top half.

You will find the dogs in the top half of the agitator.

Hope that helps.
